REGA Fono Moving Coil MK4 Phono Stage

The Rega Fono MC is an exceptionally high quality MC phono stage designed to maximise the potential of any MC cartridge..
The Rega Fono MC has been designed to be effective, easy to use, and above all, to reproduce music. The Fono MC uses the Linear Systems low noise LSK389 FET in an all discrete input stage where low noise and linearity are vitally important to get the best from an MC cartridge.
A MUSE operational amplifier is used in the RIAA equalization amplifier. Polypropylene capacitors have been used in the signal path and in the RIAA equalization circuits..
The aesthetic design of the Fono MC was as important as the quality of its electrical capabilities, so it benefits from the same aluminium case as the Rega TTPSU and Fono MM amplifier, giving it a design which offers a familiar feel and moreover brings it in line with its illustrious bigger brothers.
Frequency response (50KΩ output load) = 13Hz (-3dB) to 100KHz (-0.3dB) RIAA accuracy (50KΩ output load) = Better than +/-0.2dB 100Hz to 100KHz Power requirements = 24V AC at 150mA maximum. Only to be used with Rega PS1..
